' IN 0., OF .AMSTECRDAM, NEW YORK, A CC'RPORATION 0F NEIV YORK .ALL METAL SPOOL Application filed February 13,1929. Serial No. 339,676.

My invention relates to the art of weaving and the like whereinthe thread or cord is supplied to the looms from spools, and'it particularly has for its objectto provide a spool which is especially useful on AX- minster looms, though its employment is not to be considered as limited thereto.

Heretofore the spools so used have been made of wood or of wooden barrels with metal heads, but because of shrinkage and cracking of the'wood used in such spools they have not given entire satisfaction. In order properly to serve their purpose the spools must be of such construction that the length of the barrel, i. e. the distance between the opposed faces of the heads, must remain constant. So also must the distance between the outer or end faces of the supporting plugs for the pivot pintles or studs. WVith all wood spools andeven with spools having metal heads and wooden barrels it is not possible to maintain the said distance constant under all conditions.

It is, therefore, a prime object of my present invention to provide a spool which will overcome the defects found in. wooden spools or spools with wooden barrels.

Further, it is an object to provide a spool of an inexpensive construction, which can be manufactured at low cost and one which will last indefinitely.

Other objects will in. part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, my invention consists in the novel features of construction and in the combination, connection and, arrangement of parts. hereinafter more fully described and then pointed out in the appended claims.

In the drawings v I Figure 1 is a perspective view vention.

Figure 2 is a central vertical longitudinal section of the same.

Figure 3 is a cross section of Figure 2.

Figure 4 is a detail elevation of the yielding pintle and its supporting plug.

Figure 5 is a detail elevation of the yieldof my inon the line 3-3 secured together by spot-welding as at Each head 2 may be provided with holes 6 for the usual purpose. I

In one or both ends of the spool thus formed is forced a suitable pintle or stud carrier. lVhen the pintle or stud carrier is.

to support a yielding pintle its construction is that best shown in Figures 2 and 4, by reference to which it will be seen that the plug is composed of a body 7 having a first reduced portion 8 to constitute a shoulder 9 at its juncture with the body 7 the reduced portion 8 being adapted to be held within the hub i by retaining friction, i. e, the plug is forced into the hub. The plug is also provided with an elongated shank or second reduced portion 10 and it is chambered as at 11 to receive the pintle spring 15 and the yielding pintle 13, the latter having a collar 14 to limit its projection through the opening 12 in tle front of the plug.

In order to retain the spring in place a. bushing 16 is forced into the inner end of the reduced portion 10 of the plug and as an additional precaution against its coming out the end of the portion 10 of the plug is burred or upset at intervals as indicated at 17 in Figure 2.

Instead of using yielding pintles in both ends of the spool a fixed pintle 21 on a plug 18 maybe employed at one end of the spool. The plug 18 is held in the hub 4 at that end byretaining friction and is provided with a stop flange 19eso as definitely to locate the plug in proper positionwithin the end of thespool. The plug 18 has a reduced end or collar 20 as shown.

It will be seen from the foregoing descripplug and pintle WIS tion, taken in connection with the accompanying drawings, that by providing the barrel 1 and heads 52 of metal, the distance between the opposed faces of the heads 2 is maintained constant, there being no shrinkage due to weather conditions as often occurs in the wooden barrels.

Furthermore by providing the plugs 7 and 18 with stop shoulders or flanges at 9 and 19 respectively, the distance between the opposed faces of the plugs is maintained constant at all times.

It is to be understood that the particular dimensions of the spool may be varied to suit the conditions met with in practice as may also the proportions of the parts, and I do not desire to be understood as limited to any particular proportions.

From the foregoing description, taken in connection with the accompanying drawing, it is thought the construction and advantages of the invention as well as its utility will be readily seen by those skilled in the art.

What I claim is:

1. An all-metal spool comprising a tubu lar barrel, a pair of sheet metal heads having peripheral flanges and central tubular hubs, said hubs being pr ssed into the ends of said barrel, means permanently securing said hubs to said barrel, and pintle carrying plugs held in said hubs by retaining friction, one of said plugs comprising a flanged body having a chamber, a pintle sliding in said body and having a collar in said chamber, a spring continuously forcing said pintle outwardly, and means for securing said spring within said chamber.

An all-metal spool comprising a tubular barrel, a pair of sheet metal heads having peripheral flanges and central tubular hubs, said hubs being pressed into the ends of said barrel, means permanently securing said hubs to said barrel, pintle carrying plugs held in said hubs by retaining fric tion, one of said plugs comprising a flanged body having a chamber, a pintle sliding in said body and having a collar in said chamber, a spring continuously forcing said pintle outwardly, and means for securing said spring within said chamber, said last named means comprising a bearing bushing held in said plugs chamber with retaining friction.

3. An all-metal spool comprising a metal tubular barrel, a pair of metal heads each having a central tubular hub tightly fitted into the ends of said barrel and spot-welded thereto, bearing plugs having smooth cylindrical surfaces tightly pressed into said hollow hubs to be there held by retaining frictional contact between the smooth surfaces of the plugs and the inner surface of the tubular hubs of the heads.

4:. In an all-metal spool comprising a metal tubular barrel, a pair of metal heads each having a central tubular hub tightly fitted into the ends of said barrel, means permanently securing said barrel and said hubs together as an integral structure, and bearing plugs having smooth cylindrical exterior surfaces to fit tlghtly into said hubs, the plugs being forced into the hubs under pressure so as to be held therein solely by retaining friction.

5. In an all-metal spool comprising a metal tubular barrel, a pair of metal heads each having a central tubular hub tightly fitted into the ends of said barrel, means permanently securing said barrel and said hubs together as an integral structure, and bearing plugs having smooth cylindrical exterior surfaces to fit tightly into said hubs, the plugs being forced into the hubs under pressure so as to be held therein solely by retaining friction, the plugs having flanges to engage the hubs of the heads to limit the penetration of the plugs into the hubs.
